PDF-Most seismometers detect ground motion using a mass that is suspended

1 Background fashion by a spring When the ground moves the seismometers frame also moves The mass tends to remain relatively still however because of inertia The relative motion of the ma.

MEASURING GROUND MOTION. The first known instrument for earthquakes measurement is the Chang seismoscope built in China in 132 B.C. .
